'lO ALL PER-SONS T0 WHOM THESE PRESENTS SHALL COME:r I

Be it known that I, ALBERT BINGHAM, of Newtonville, in the county of Middlesex,` and- State of Massachusetts, hn-ve invented :tn Iniproved Blind-Fastener; :md do hereby declare the sume to be fullydescribed in the following specification, and reprcsentcdin the accompanying drawings, of which-4 v Figure l is u side view of it as applied to :t blind and its window-sill.

Figure 2 is afront end view of it under like circumstances.

Figure 3 is a ltransverse section taken through the step of the cutch-lever.

Figure 4 is on under side view of the catch-lever.

In suoli drawings, A denotes the bottom har oi' o. window-blind, and B represents the window-sill. C is what I term the catch-lever, which is arranged underneath the bottom barof the bli=id,nnd is connected thereto by a screw, a, which goes up through a. hole, b, made through the catchelever ner its rear end. The screw is screwed up into the bottom bnr so that the catch-lever, while resting on the head of the screw, will be free to play up and down one stop, D, which extends down from the bottom bar, and through a` slot, c, made in the catch-lever. At its rear end the cntch-lever is provided with an arm,d, which rises vertically from it and alongside the inner face of the bottom bn-r. By taking hold of the said arm and movingit, n, person 4may easily disengage the catch-lever from the catch E, which projects upward from the window-sill.` The cntch-lever at its front end is provided with n projection, e, which is formed withu notch,f. and two cams or liftersgrg, to flank such notch, the whole being as represented in figs.. 1,2, und 4. Furthermore, the stop D has two'shoulders h h, projecting from opposite' side of it, the lower edges of such Shoulders being on :t level with the top fof the catch I I i Figure 5 is a. top view, and

Figure 6 :t sideview of the catch which is to be driven into the wall of the building in order to hold the blind open. Y

When the blind is closed the stop D brings up against the catch', and one of the shoulders h k rests directly on the top of the catch, und serves to support therblind so as to prevent it from sagging. The catch-lever will take upon the catch and hold the blind closed, The operations of the catch-lever audit-he stop with the wall catch will be the same as with the sill catch, the blind when the stopis against either catch being supported thereon so as to be prevented from sagging.

I claim the blind-fastener as composed of the catchlever C, the stop B, its shoulders Vh It, and the catch E, arranged and constructed so als to be applied to a. blind anda windowfrrtme or sill, substantially as specied.
